This lesson primarily focuses on 4.NBT.B.4 - fluently adding and subtracting multi-digit numbers using the standard algorithm.  The lesson connects to and builds on students' understanding of place value and the base-ten number system (4.NBT.A.1).  Students use a step-by-step process to add and subtract multi-digit numbers, as modeled by the teacher.  Students then work through word problems that require use of the standard algorithm, first with partners and then independently.
